中国云南西部 (滇西 )三江地区是地史时期冈瓦纳大陆与劳亚大陆相交接的古缝合线地区之一 .在滇西腾冲地区及保山地区所谓的冰碛物地层内 ,相继处理出冈瓦纳型孢粉 ,并将它们对比为澳大利亚早二叠世的孢粉Stage 2或Pseudoreticulatisporaconfluens带的一部分 .滇西腾冲、保山所发现的孢粉新资料进一步证实和补充了Kemp关于Stage 2广泛地理分布的论断 .鉴于这些孢粉主要产自于冰碛物层序中的冰消期 (deglaciation)层序内 ,将它们命名为整个冈瓦纳大陆二叠纪最早孢粉事件并赋于其古气候内容 .温暖水动物出现在该层位之上 .这又一次证实了在经历一次灾难性事件后 ,植物较动物更早复苏 .
Sanjiang, western Yunnan (western Yunnan), is one of the ancient suture intersected between Gondwana and Laurasia in the Geolithic Period. Within so-called tundra strata in the Tengchong and Western Baoshan areas in western Yunnan, The Gondwana sporopollen is compared with that of the Permian Stage 2 or Pseudoreticulatis poraconfluens in the Early Permian, Australia. The new sporopollen found in Tengchong and Baoshan, Western Yunnan further confirmed and supplemented Kemp’s Geographical distribution of these pollens.Because these sporopollen mainly originated in the deglaciation sequence in the moraine sequence, they were named as the earliest sporopollenic event in the Permian of the Gondwana continent and endowed with it Paleoclimate Contents Warm water fauna appears above this horizon, confirming once again that plants recovered earlier than animals after a catastrophic event.
